C-Scan package is designed to interface to a new or existing ultrasonic
scanning system. It can be supplied to work with the existing
ultrasonic flaw detector system. Alternatively a new PC based
system can be supplied, as required.

system has a nominal resolution of 0.25mm in both the X and Y
directions. Scans can be made by scanning in the X direction and
index in the Y direction or vice versa. C-Scan data can be collected
on the left to right scan, right to left scan or in both directions.

memory. These stored scans can then be recalled and re-displayed
using variable threshold levels and colours.

maximum displayed area is pre-set for each system, and is determined
by the area of the scanning tank to which the system is fitted.
displayed area for a particular scan can be manually entered or
automatically captured during the initial set-up. In all cases
the C-Scan data is stored with a resolution of 0.25mm in the X
direction and a maximum resolution in the Y direction. The Y direction
resolution is dependant on the selected index.
relating to the test can be entered and saved together with the
C-Scan image it’s self. This information is also printed
to 10 threshold levels and colours associated with these levels
are provided. Both the threshold level and the associated colour
may be selected and changed as required.
system also calculates the percentage area of each threshold in
the scan, which is then displayed. These percentage figures are
updated if the zoom level is changed, since the calculation for
this is based on the displayed image.

Simply select the required threshold level to which you require
the defect to be measured, and then drag a box around the required
defect. The resultant measurement is displayed as shown;
